AC-AREAS
Armor is now divided into areas of your body. Specifically, HEAD, BODY, RIGHT-ARM, LEFT-ARM, RIGHT-LEG, and LEFT-LEG. These areas will contribute to the realism and the playing experience of the mud, making it much more real. This means that you can be hit in specific areas of your body, so damage taken is directly related to the properties of the item(s) worn on that area, if any.
This means that different areas of your body will have different levels of protection, depending on the items you have. If an item has AC, then the AC on it is local just to that area. If the item has ALL-AC, then your _total_ AC will be adjusted accordingly, for all areas of your body. The actual amount of AC on a particular area of your body is the sum of the area AC for the item(s) worn on that area, and your ALL-AC, which is the AC that affects your whole body. (such as from the 'Armor' spell)
For example, if you are attacked in the HEAD area: The AC that the hitroll must pass will be the sum of your ALL-AC and and the AC of the item(s) being worn on your head. Damage incurred will be lessened by the sum of your ALL-STOPPING and the STOPPING of the item(s) being worn on your head. Resists, immunities, and susceptibilities that affect the item(s) OR your whole body are also taken into account.
HINT: Shields give ALL-AC, making their coverage global.
